What it means
When the seller has a Swedish address and a VAT number (BT-31) that starts with SE, the rule takes up to 12 characters starting at position 3 and tries to convert them to a number. It fails if that part cannot be read as a number. It does not check the total length or require every checked character to be a digit. Leading or trailing whitespace within the extracted part does not by itself cause failure.
Why it matters
Peppol BIS Billing 3.0 requires the checked part of the VAT number to be numeric when the seller has a Swedish address and the number starts with SE.
How to fix it
Check the VAT number in your seller or company settings. Type it as SE followed by 12 digits, with no spaces or hyphens, for example SE556677889901. A letter O typed instead of a zero also fails.
